Abstract: A unit testing framework automatically issues a call to a remote testing automation framework on an originating system to automatically execute a functional test script specified in a unit testing framework test case through a functional testing framework on a target on a remote system. The originating system automatically issues a call to the remote testing automation framework to copy a functional test log resulting from executing the functional test script from the remote system to the originating system. The unit testing framework automatically evaluates whether the functional test log comprises at least one error. The unit testing framework, responsive to the functional test log comprising at least one error, automatically marks the unit testing framework test case as failed.

Abstract: Systems and methods for providing for efficient switchover for a client in a storage network between the use of one or more a primary storage resources to one or more disaster recovery (DR) resources are provided herein. Embodiments may implement synchronization between such resources on a data plane and a control plane to allow for a transition between resources to be implemented in a manner that is minimally disruptive to a client. Moreover, embodiments may provide for processing resources which allow for switching a client between a primary storage resource to a secondary storage resource with minimal administrative interaction.

Abstract: One or more techniques and/or systems are provided for hosting a virtual machine from a snapshot. In particular, a snapshot of a virtual machine hosted on a primary computing device may be created. The virtual machine may be hosted on a secondary computing device using the snapshot, for example, when a failure of the virtual machine on the primary computing device occurs. If a virtual machine type (format) of the snapshot is not supported by the secondary computing device, then the virtual machine within the snapshot may be converted to a virtual machine type supported by the secondary computing device. In this way, the virtual machine may be operable and/or accessible on the secondary computing device despite the failure. Hosting the virtual machine on the secondary computing device provides, among other things, fault tolerance for the virtual machine and/or applications comprised therein.

Abstract: A method supports data communication in a mobile application by specifying in the mobile application a program intent and one or more course or fine-grained properties of data objects in terms of tolerance to delay and loss; selecting a transfer policy for a set of data objects based on the application intent; receiving and coalescing intents of one or more applications for object data for the one or more applications; crafting an aggregate transfer policy, and communicating data from one or more applications as an aggregate based on the aggregate transfer policy to programmatically incorporate and benefit from tolerance to delay in the transfer of data.

Abstract: Methods, systems, and computer readable media for adjusting load at a device under test are disclosed. According to one method, the method occurs at a testing platform. The method includes determining whether a current operations rate associated with a device under test (DUT) is near a target operations rate, wherein the current operations rate is associated with one or more simulated users being simulated by the testing platform. The method also includes adjusting the current operations rate by increasing or decreasing the number of simulated users interacting with the DUT in response to determining that the current operations rate associated with the DUT is not near a target operations rate.

Abstract: Activity-based sampling provides useful and relevantly focused diagnostic data, connected to improve a developer's understanding. An application invokes log-event procedures, causing a logger to check logging conditions and make a log entry when a logging condition is satisfied. The logger has a set of log-enabled activities, and one or more start-events with respective sampling frequency conditions. One logging condition is that a current activity-id be log-enabled. Another states that if the current activity-id is not log-enabled but the log-event procedure identifies a start-event consistent with the sampling frequency condition, the activity is log-enabled and a log entry is made. Creation of a child activity by a parent activity which is in the set of log-enabled activities is noted in the log, and the child is automatically log-enabled. A log consumer may reside inside or outside the application. Event Tracing for Windows services can be enhanced to support activity-based sampling.

More specifically, embodiments of this archive verification can comprise loading media into a drive and reading data from the media to verify that the media and data on the media can be read. In one embodiment, media can be loaded into a drive and read according to a verification policy. As part of verifying that media and data on media can be read, read errors or other verification data associated with media can be obtained. Using this verification data a result for the media may be determined.

Abstract: The concept of faults and fault handling are added to the execution of continuous event processing (CEP) queries. By introducing fault handling techniques to the processing of CEP queries, users are enabled to instruct a CEP query processor to respond to faults in a customized manner that does not necessarily involve the halting of the CEP query relative to which the faults occurred. For example, a fault might be due to a temporary problem. Under such circumstances, the CEP query processor can be instructed to ignore the fault and allow the execution of the CEP query to continue relative to the remainder of the event stream. Alternatively, if the fault is due to a problem with the CEP query itself, then the CEP query processor can be instructed to propagate the fault through the query processing system until the fault ultimately causes the problematic CEP query to be halted.

Abstract: Storage system comprises a second storage apparatus, which is coupled to multiple first storage apparatuses and is of a different type from the first storage apparatuses, and a first control device, which exists either inside or outside of the second storage apparatus. Row of stripes comprising multiple data elements obtained by segmenting a prescribed data unit, and a redundancy code for rebuilding the data elements, is distributively stored in multiple first storage apparatuses, which are more numerous than the total number of stripe data elements, which are either the data elements or redundancy code, in the row of stripes. The row of stripes is configured to enable the rebuilding of the stripe data elements even when a failure has occurred in up to a prescribed allowable number, which is two or more, of the first storage apparatuses storing the stripe data elements of the relevant row of stripes.

Abstract: A method begins by a processing module dispersed storage error encoding data to produce encoded data slices and updating directory metadata regarding storing the data in a dispersed storage network (DSN) memory to produce updated directory metadata. The method continues with the processing module dispersed storage error encoding the updated directory metadata to produce encoded directory metadata slices and transmitting one or more data slice write requests to the DSN that each include a first transaction number. The method continues with the processing module transmitting one or more directory metadata write requests to the DSN memory, wherein the one or more directory metadata write requests includes a second transaction number, and when a favorable write response condition exists, transmitting a commit request to the DSN memory to commit storage of at least one of: the encoded data slices and the encoded directory metadata slices.
